Question
a volleyball player makes a diving save and hits the ball upward right before it hits the ground on her teams side. the balls height above the ground in feet can be modeled by the expression -16t² + 32t + 2, where t is the time in seconds after the player hits the ball. what does the number 2 represent in the expression? the height in feet of the ball when the player hits it the time in seconds from when the player hits the ball until it reaches its highest point the time in seconds from when the player hits the ball until it hits the ground the height in feet of the ball when it reaches its highest point
Step1: Analizar la función cuadrática
La expresión \( -16t^2 + 32t + 2 \) es una función cuadrática que modela la altura del balón en función del tiempo \( t \) (en segundos). En una función de movimiento vertical (como el lanzamiento del balón), el término constante representa la altura inicial cuando \( t = 0 \).
Step2: Evaluar en \( t = 0 \)
Sustituimos \( t = 0 \) en la expresión: \( -16(0)^2 + 32(0) + 2 = 0 + 0 + 2 = 2 \). Cuando \( t = 0 \), es el momento en que el jugador golpea el balón, por lo que la altura en ese instante es 2 pies.
